Context & Job Description :

As an IT Cyber Security Engineer, you will play a key role in protecting our organization’s information systems and data. You will be responsible for developing and implementing security policies and procedures, managing security projects, and responding to security incidents.

As our company and cybersecurity team are still small, we’re looking for a versatile, hands-on security expert—a true Swiss Army knife who is comfortable wearing multiple hats. You will act as blue team, red team, and purple team all at once, proactively defending, testing, and improving our security posture.

Our infrastructure is 100% cloud-based, spanning multiple vendors. To ensure robust security and scalability, we aim to process and automate as much as possible—from threat detection and response to compliance and infrastructure hardening. You will play a key role in designing and implementing automated security solutions that enhance protection while reducing operational overhead.

This role is perfect for someone with a strong technical background who thrives in dynamic environments, enjoys stepping outside their comfort zone, and is eager to explore new areas of cybersecurity.

Through this position you will report directly to our CISO, and work closely with:

• 
  The tech & product teams to help implement security best practices for software development


• 
  Greenly employees to investigate security alerts.

If you have a hacker mindset, a passion for security, and the willingness to tackle challenges across different domains, we want to hear from you!

• 
  Infrastructure: Our robust cloud infrastructure is built on Google Cloud Platform for scalability and reliability, with Terraform enabling infrastructure-as-code practices for consistent deployments. We leverage Kubernetes for container orchestration and automated scaling, while Cloud Run provides serverless compute capabilities for specific microservices.
